IBOTTLE-STOPPER.

Specification of Letters Patent.

Patented Sept. 24,1912.

Application filed December 28, 1910. Serial No. 599,666.

To all whom it may concern:

Be it known that I, CHARLES A. NATT, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Bottle-Stoppers, which improvement is fully set forth in thefollowing specification and shown in the ae companying drawings.

The present invention relates to bottle stoppers and more particularlyto the type in which the stopper is provided with a discharge that iscontrolled by a valve which opens to discharge the contents of a bottleto which the' stopper is applied, and closes when the bottle isuprighted, keeping dust and other extraneous matter from the contents ofthe bottle.

An Object of this invention is to form inexpensively' the main portionsof the stopper from sheet metal and connect its parts in such a mannerthat the use of solcler is unnecessary.

Another Object is to provide for securing a guide member for the valvewithin the stopper in such a manner that it will be held firmly inposition against displacement without the use of solder or the like.

To these and other ends the invention consists in certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings, Figure 1 is an enlarged side view of a bottle stopperconstructed in accordance with this invention; Fig. 2 is an enlargedvertical or axial section; Fig. 3 shows in enlarged side elevation thecasing members separated with the guide member located between them; andFig. l is a detail top view of the guide member.

In carrying out the invention there is employed a easing having achamber 1. The casing preferably is forrned of two members each stam'pedfrom a single blank of Sheet metal. One casing member embodies asemispherical portion 2 having an inlet or tubular portion 3 drawntherefrom, the latter being surrounded by an externally tapered sleeve 4of cork or other suitable material to fit within the mouth of a bottle.The other casing member has a semispherical portion 5 united to thespherical portion 2 and provided with a discharge Opening 6, the latterbeing surrounded preferably by a flaring flange 7 serving as a valveseat. The

seam ,between the casing members preferably is permanent and is formedby an outwardly turned or flaring flange 8 on one of the membersreceived within and surrounded by an enlarged portion 9 on the othermember.

The discharge is preferably closed by an inverted cone shaped valve 10which is held to the seat 7 by a weight 80, the latter being connectedto the valve by a stem 11 and having ribs 12 on its under side to seatin the upper end of the tubular portion 3 when the valve 10 is closed.It is apparent that if the bottle, in which the stopper fits, be tiltedto discharge its contents, the weight will move in the chamber of theeasing and displace the valve from its seat and that when the bottle isuprighted the weight will draw the valve to the seat.

To the end that the valve will move upwardly out of the path of theoutflowing liquid, a guide member coperates with the stem 11 between theweight and the valve. The guide member, in this instance, comprises aguide or bar 13 having a perforation or Opening 14 on which the stemloosely works, said guide being rigidly secured at its ends to a ringmember 15 which may be in the form of a ring segment of a sphere so asto eonform to the inner wall of the spherical chamber about the seam.Preferably the guide bar and the ring member are formed from a flatpiece of material pressed into cup shape and perforated to form the bar13, so that the bar lies in the plane of one edge of the ring.

The guide member may be secured to the walls of the chamber without theuse of solder and to this end may have portions lying between the twomembers of the casing in engagement with the annular shoulder 17 on onemember and the flange 8 on the other member, such portions of the guidemember being in this instance in the form of an outwardly turned annularflange 18 on that edge or ring 15 opposite the bar 13, so that the seambetween the casing members is also utilized for holding the guide memberagainst movement.

The operation of the device has been set forth in detail in theforegoing description but it may be, at this point, stated that thetilting of the bottle, in which the stopper is arranged, causes thevalve 10 to leave its seat and move upwardly, permitting the pouring ofthe contents of the bottle, and

that when the. bottle is uprighted the .weight 80 draws the valve to itsSeat. When the valve 10 coperates With its seat 7 the lugs 12 seat inthe upper end of the tube 3 so that any liquid within chamber l may runback into the bottle. When the valve is tilted theselugs coperate withthe bottom wall of chamber 1 and kick or project the valve from its seatso that there will be no binding action ,between the valve and itsseat'and the valve stem and its guide.

The construction herein described permits the stopper to be madeinexpensively from aluminum a result which is very desirable, as nickel,iron and other metals are quickly discolored by 'whiskies' and similarliquids. At the present time it is not practical to solder aluminum on acommercial scale and this device entirely dispenses with the use ofsolder in its manufacture.

What- I claim as my invention or desire to secure by Letters Patent,is-- 1. A bottle stopper comprising a pair of members coperating toprovide a chamber, one of said members being provided with a dischargeand the other being provided with an inlet, a valve for the discharge, aweighted stem on the valve, .and a guide member coperating with the stemand having portions extending downwardly therefrom and held between andengaged by the two chamber forming members.

2. A bottle stopper comprising a pair of members coperating to provide achamber, one of said members being provided with a discharge and theother being provided wit-h an inlet, a valve for said discharge, aweighted-stem connected to the valve, and a guide member including aring engaged and held by both chamber forming members, and a guidecarried by said ring above the connection between the members.

3. A bottle stopper comprising a pair of members coperating 'to providea chamber, one of said members being provided with a discharge and theother being provided With an inlet, a valve' for said discharge aweighted stem connected to the valve, and a guide member including aguide and a ring supporting said guide and having a fiange at its lowerend arranged between and engaged by the two chamber-torming members andalso having a portion conforming to and tightly fitting to the innerface of the chamber above the flange.

4. A bottle stopper comprising a spherical chamber having a discharge atits top, a valve for said discharge, a weighted stem secured tosaidvalve, a ring segment of a sphere having its entire outer facetightly fitting the inner walls of said chamber, and a guide rigidlysecured to said ring segment and coperating with the valve stem.
